Some information on US equity market.
Schedule 13D is an SEC filing that must be submitted to the US Securities and Exchange Commission within 10 days, by anyone who acquires beneficial ownership of more than 5% of any class of publicly traded securities in a public company. A filer must promptly update its Schedule 13D filing to reflect any material change in the facts disclosed, including, among other things, the acquisition or disposition of 1% or more of the class of securities that are the subject of the filing.
13D filings allow the investing public to see who a public company's large shareholders are and, perhaps more importantly, why they have an interest in the company. These filings may be a precursor to hostile takeovers, company breakups, and other "change of control" events.
